But most of the work we do in real life is 2D. Record keeping, accounting, writing correspondence, writing reports. The type of work that could benefit from 3D, like architecture, engineering, medicine -- those kinds of works are practiced by much less people than just boring 2D work. I think for virtual/argumentative reality platforms to go mainstream, it has to make boring 2D work just a little bit better for people, by subtly adding 3D elements to mostly 2D work. Like hopefully, having lots of 2D windows floating around in 3D space makes it easier to keep them organized and to find the right window when you need it.
